報錯信息

在 Windows 下的 Conda 環(huán)境中pip install一些需要現(xiàn)場編譯的庫時經(jīng)常會報錯：

上圖為安裝pyopenjtalk時的報錯信息。

規(guī)避方法

我之前遇到這種問題的解決方法是直接下載已經(jīng)在Windows上編譯好的whl文件，然后：

pip install xxx.whl

然而該網(wǎng)站并沒有編譯好的pyopenjtalk包，因此這次必須解決該錯誤。

問題原因

根據(jù)微軟官方問答平臺中的說法，應(yīng)該是Conda環(huán)境下pip的構(gòu)建工具選擇錯誤。

解決方法

在pip install之前執(zhí)行：

SET DISTUTILS_USE_SDK=1 & "C:\Program Files (x86)\Microsoft Visual Studio\2019\BuildTools\VC\Auxiliary\Build\vcvarsall.bat" x64

注意vcvarsall.bat的路徑因人而異。

至于為什么要這么做，可以參考下sklearn的高級安裝文檔。文章來源地址http://www.zghlxwxcb.cn/news/detail-539029.html

到了這里，關(guān)于已經(jīng)安裝vs依然顯示error: Microsoft Visual C++ 14.0 or greater is required.的文章就介紹完了。如果您還想了解更多內(nèi)容，請在右上角搜索TOY模板網(wǎng)以前的文章或繼續(xù)瀏覽下面的相關(guān)文章，希望大家以后多多支持TOY模板網(wǎng)！
